COMBINED CORNER-IRON AND TIGHTENING DEVICE FOR WIRE MATTRESSES.

SPECIFICATION forming part of Letters Patent No. 396,122, dated January 15, 1889. Application filed March 27, 1888. Serial No. 268,624. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES H. TRIPHAGEN, a citizen of the United States, residing at Portland, in the county of Ionia and State of Michigan, have invented certain new and useful Improvements in a Combined Corner-Iron and Tightening Device for YVire Mattresses, of which the following is a specification, reference being had therein to the accompanying drawings. I

This invention relates to new and useful improvements in mattress-frames for stretching woven wire or other elastic fabric; and the invention consists in the peculiar construction whereby the parts of the frame are secured together and the woven wire or other elastic fabric used in the construction of the mattress may be stretched whenever it becomes slack, all as more fully hereinafter described.

In the drawin which accompany this specification, Figure 1 is a longitudinal section through a mattress-frame embodying my improvements. Fig. 2 is a cross-section thereof on line 00 .r. Fig. 3 is a section thereof on line 1/ y, Fig. I. Fig. 4 is a detached perspective view of the parts forming the adjustable crossbar support in detail, and Fig. 5 is a detached perspective view of the non-adjustable crossbar support.

A are the longitudinal bars, and B are the cross-bars, of the ordinary mattress-frame, except as hereinafter described. The cross-bars B are secured at the corners to the longitudinal bars by means of the cast-iron supports, consisting of the bracket or standard 0, provided with suitable m eanssuch as the flanges atogether with suitable bolts, b, to firmly secure them to the longitudinal bars A.

D are corner-irons for securing the crossbars thereto. For one end of the frame these corner-irons may be made integral with the brackets C, as shown in Fig. 5, and for the other end of the frame they form a separate casting, as shown in Fig. 4, and which is rotatably secured to the upper end of the standard C by means of suitable screw-bolts, E, or

otherwise, which pass through coincident holes in the standard of the corner-irons and enter the cross-bar to form a pivotal bearing therefor. The spring bolt or latch G is secured in the corner-iron in a suitable seat formed in the corner, and this boltis adapted to engage in one of the series of adjustingholes H, formed in the standard C. The cornerirons D are provided with suitable bolt or screw holes, 0, to bolt or screw the end of the cross-bar thereto, and the spring-latch G is provided with a suitable finger-piece, d, by means of which the bolt is operated.

In practice, the parts being arranged. and constructed as shown and described, the woven-wire fabric is secured to the cross-bars in the ordi n ary in an ucr, and it will be seen that by means of the adj ustahility provided by the supports at one en d of the mattress-frame arotary adjustability of one of the cross-bars is obtained, by means of which the fabric may be stretched when it becomes slack, the bolt G holding it in its adjusted position.

It is obvious that all four of the corner-supports maybe made adjustable in this manner; but, for the sake of economy and simplicity, Iprefer to apply the adjusting devices only to the supports of one cross-bar.

\Vhat I claim as my invention is The combination,.with the side and cross bars of a mattress-frame, of the sets of brackets 0, provided with flanges a and secured to said side bars, the set of brackets at one end of the frame being provided with the cornerirons, to which the cross-bar B is secured, the brackets at the opposite end of the frame provided with adjusting-holes, and the cross bar j ournaled therein and having the lockinglatch G, which engages the adjusting-holes, substantially as described.

In testimony whereof I affix my signature, in presence of two witnesses, this 31st day of December, 1887.
